る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a traffic signal controller for controlling traffic flow at intersections. In snowy countries where there is a lot of snowfall during the winter, snow adheres to traffic signal lights, causing visibility problems (the blue, yellow, and red signals are obscured by the falling snow), and bending of the traffic light beams due to heavy snowfall. There is. In order to prevent problems such as -, it has been considered to melt the snow by providing a heat generating source in the eaves of the light fixture or in the light fixture that houses the light fixture.

融雪を行なう交通信号制御機が提案されている。The present invention switches the heat generation source according to the intensity of snowfall, and attaches it to traffic signal lights with less electricity.Conventionally, for the purpose of melting snow, a heat generation source such as a heater is embedded in the eaves, etc., and the heat generation source is turned off by 0N10FF. A traffic signal controller that melts snow on the eaves of light equipment has been proposed.

から、雪が積らないのにヒータに通電されたり、雪が残
っているのに通電が切られたりするということが生じ、
無駄な電力エネルギーを消費してまう欠点があった。However, in the above-mentioned conventional traffic signal controller, snow melts using at least the same amount of power as snow melting, so power may be turned on to the heater even though no snow has accumulated, or power may be turned off even though snow remains. This happened,
It has the disadvantage of consuming unnecessary electrical energy.

深くなる。Figure 1 is a graph of data obtained through experiments on the relationship between the depth of snowfall and the depth of snow on the eaves of traffic signal lights. According to this, the depth of snowfall is about % of the depth of snowfall, and naturally, the deeper the snowfall, the deeper the snowfall.

る。The present invention focuses on such natural phenomena, and uses a snowfall intensity meter that uses reflection of infrared light, etc., and switches the heater depending on whether the snow depth is 5 crn or more or less, for example, as shown in Figure 1.
This is an attempt to achieve reasonable snow melting using less electricity.

チ４−・ａ、４−ｂが閉となる。An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. In FIG. 2, reference numeral 1 denotes a snowfall intensity meter that measures the intensity of snowfall using reflection of infrared light, etc., and the output level of this snowfall intensity meter changes depending on the intensity of snowfall. 2
, 3 is a comparator, and 10.11 is a power supply that provides a reference level for the comparator 2.3. For example, comparator 2 sets a reference voltage level corresponding to snowfall of 2 cm or more, and comparator 3 sets a reference voltage level corresponding to snowfall of 6cfn or more. Comparator 2 above
．． 3, an output occurs when that reference voltage level is exceeded. Reference numeral 4 denotes a changeover switch device, and in this changeover switch device, the respective switches 4-, a, and 4-b are closed according to the outputs of the comparators 2 and 3.

に除去できるものである。Next, the operation of the above embodiment will be explained. For example 2t1
When there is a snowfall of n or more and snow accumulation is likely to occur, the comparator 2 is activated, the switch 4-a is closed, and the heater 6 is energized to generate heat and melt the snow. On the other hand, 5crn
If the snowfall is heavy, exceeding the above, switch 4-a.
, 4-b are both closed, and both heaters 5 and 6 are energized,
The snow melting effect is further promoted. As mentioned earlier, visibility problems caused by snow hanging down from the eaves 8 can be effectively resolved by energizing the heater 5 installed on the outer periphery of the eaves 8 to melt the snow in this area before the amount of snow accumulates. According to this embodiment, the above-mentioned visibility disorder can be particularly effectively eliminated.

予想されるような降雪ではヒータを働かせることはなく
、無駄な電力を投入することはなくなり省電力化が可能
となるものである。As described above, the present invention switches the heat generation source such as the heater according to the output of the snowfall intensity meter, and in the case of snowfall that is not expected to result in snowfall, the heater is not activated, thereby wasting power. This eliminates the need to do so, making it possible to save power.

数本であればよいものである。Note that the embodiment shown in FIG. 3 uses two heaters,
However, the number of heaters is not limited to two, but may be more than one.
